Introducing geometry objects

Geometry objects are a collection of coordinates that describe where something is in the world. They give shape to the data we're looking for. They can be used for displaying graphics on a map, or to provide spatial data for queries, or even for geoprocessing services. Geometry objects come in five basic types: point, line, polygon, extent, and multipoint. Any shapes are built on these basic types. Let's take a closer look.

Point

In the ArcGIS API for JavaScript, a point is the simplest geometry object. It contains the x and y coordinates of the point, as well as the point's spatial reference. A point can be constructed with x and y coordinates, plus a spatial reference. It can also be defined by longitude and latitude.

Polyline

A polyline geometry is a collection of one or more arrays of point coordinates. Each array of point coordinates is called a path, and would look like a line when drawn out. Multiple paths can be stored in the same geometry, giving the appearance...
